Has. Huaylluay, near Pasco; at an elevation of from 12,000 
to 14,000 feet above the level of the sea. 
This species so nearly accords with the A. glaucescens, 
Humb. and Kunth, that both Mr. Cruckshanks and myself 
doubted at first if it ought not to be considered identical with 
it: but the form of ilie inner segments of the perianth is so — 
very different, that we have thought it safer to describe it as 
-a distinct species, to which we have given the name of A. 
dulcis, on account of the sweet pulp, with which the seeds 
are surrounded, and which are eaten by the native children 
of the elevated regions which it inhabits.
